NGC 676 is a lenticular[6] Seyfert 2 galaxy[4] in the constellation Pisces.[2] Its velocity with respect to the cosmic microwave background is 1217 ± 20 km/s, which corresponds to a Hubble distance of 58.6 ± 4.2 Mly (17.96 ± 1.29 Mpc).[2] In addition, two non redshift measurements give a distance of 61.0 ± 2.6 Mly (18.7 ± 0.8 Mpc).[7] The galaxy was discovered by German-British astronomer William Herschel on 30 September 1786.[8]
NGC 676 can be seen near the star α Piscium.[6] Located close to the celestial equator, it is visible from both hemispheres.[6] BD +04 0244, a star with a visual magnitude of 10.44, is superposed 5.1 arc seconds south-southwest of the nucleus.[2] It is one of the 621 galaxies described in Marat Arakelian's catalog of high-surface-brightness galaxies.[5]
